Central to Spinoza’s ethical theory is a model of human nature: the model of the free man. In this paper I argue that the idea of the free man is an inadequate idea when this is understood as the idea of a perfectly free finite thing. But when properly understood--that is, when the idea of the free man is understood as the idea of the perfection of our nature and power--the idea of the free man is a way of conceiving God and is, as such, an adequate idea.
